The Gigamail requires the same configuration as the other domain email accounts on mail Clients. With it, you can also activate the Antivirus & Antispam service.

Here below are the parameters you must use to configure the email client

Incoming mail(POP3):
Outgoing mail(SMTP): (only if you connect using or if you use the Antivirus & Antispam service)
Account Name:
Password: the one you selected for the account

Attention: you can only use the outgoing mail server (SMTP) related to your domain if you  connect through, if not you need to contact your ISP.
